Coronavirus: Everything You Need To Know-WHO

Background of Corona Virus


It is a respiratory disease that was first detected in China at the end of December 2019. It is caused by a new coronavirus whose outbreak was firstly observed in Wuhan city of China. And it became more severe in very less time in more locations internationally. The virus has given the name "SARS-CoV-2" (Severe Acute Respiratory Syndrome) and the disease caused by virus stated as "coronavirus disease-2019" abbreviated as " COVID-19 "by WHO. Around, a total of 75,465 COVID-19 cases were reported only in china as of 20 February 2020.

The Virus


Coronavirus is a zoonotic virus. A zoonotic disease is an infectious disease caused by viruses, bacteria, or parasites that find their routes from vertebrates(nonhuman animals ) to humans. Some examples of zoonosis are- Ebola virus and Salmonellosis.  Simply, these viruses are exchanged between animals and humans.
A coronavirus is a group of a large family of the virus which is most common in humans and many different species of animals like camel, cattle, cats, and bats. Animal coronaviruses can get combined with a human because of direct contact or transmission ( as China is having a seafood market or live animal market making an easy way for the animal-to-human spread).  As per reports, the main source or origin of this "SARS-CoV-2"   virus possibly be "bats".

Symptoms


As coronaviruses are a large family of viruses causing illness ranging from minute cold to more severe diseases like this novel (new) coronavirus also called nCoV.Common indication towards infection include respiratory symptoms as that for a cold are-
  • Fever.
  • Cough.
  • Uneasiness in breathing.

In more severe cases, symptoms are:-

  • Pneumonia.
  • SARS(Severe Acute Respiratory Syndrome).
  • Kidney failure and even death.

In case of any of these symptoms, do visit the nearby hospitals for consulting doctors and take tests so as to have a clear view. And do avoid public gatherings if suspected.

Routes of transmission


  • In general, human-to-human transmission of the COVID-19 virus is mainly due to close unprotected contact between contagious disease and infected(within 6 feet).
  • When an infected person sneezes or coughs the respiratory droplets that infected person-produced is directly inhaled by another person within 6 feet and hence it enters the lungs of a healthy person.
  • Contact with contaminated surfaces or objects.


Recommendation and advice for the public by WHO


Some standard recommendations for the prevention of this infection spread include-
  • Washing your hands properly using soap, sanitizers, etc.
  • Cover your mouth and nose when sneezing and coughing,  so as to avoid transmission of bacteria or virus from person-to-person.
  • Do avoid contact or close contact with any person showing signs of respiratory problems like coughing and sneezing primarily.
  • Gently cook meat and eggs. Don't go for half-raw or half-cooked meat or any type of seafood nearby epicenter city of an outbreak or in any affected region.
  • Avoid touching your face, eyes, nose, and ears frequently.
  • Avoid unprotected contact with farm or wild animals.
  • Lastly, don't panic in this kind of situation. Do follow prevention measures, but don't blindly follow unnecessary myths for prevention.


Common Questions 


Q1. Can Someone Spread the Virus without being Sick?

Ans Yes, It is true that someone may spread the virus without being Sick. There are some cases in which a person spread before showing the symptoms of this new coronavirus. 

Q2. How Easily the Virus Spreads?

Ans Spreading of Viruses is a measure of two factors:
  • How much Contagious?
  • How much Sustainable?
The virus that causes COVID-19 seems to be highly contagious i.e spreading easily and it also sustainably spreading in the community.

Q3. Did we want a medical certificate to show in airports that we are not affected by coronavirus?

Ans The answer is No, there will be a check at the airport where 
All incoming passengers will be investigated and then they will separate the infected for further treatment. Whenever our immune system finds any harmful bacteria or virus it starts increasing body temperature or cold, cough, etc. These symptoms will be detected by thermal scanners at the airport. It is not compulsory that every one those separated out have COVID-19 for sure and those who pass the check all are infection-free. Because coronavirus can only be detected in the lab.
